Description

Technical Field

[0001] The utility model relates to the technical field of line-scanning light sources, in particular to a multi-angle combined line-scanning light source. Background Art

[0002] A line scan light source is a light source used in line scan cameras or line scan sensors. It typically emits a light beam in the form of a strip or line. It is designed to illuminate a specific line of the object to be inspected, thereby achieving high-precision image acquisition. Line scan light sources are widely used in industrial visual inspection, print quality monitoring, surface defect detection and other fields. They can provide uniform illumination, ensuring image quality and scanning accuracy. However, existing line scan light sources generally can only acquire images using a single light source. A single light source may not provide uniform illumination, resulting in overexposure or underexposure in certain areas, thus affecting image quality. This is especially true when processing highly reflective or low-contrast objects. Line scan light sources generally have a fixed lighting direction, and in some cases, reflections or shadows may not be avoided, affecting image clarity and detail capture.

[0003] In view of this, we propose a multi-angle combined line scanning light source. Utility Model Content

[0004] In response to the above-mentioned shortcomings of the existing technology, the utility model provides a multi-angle combined line scanning light source, which can effectively solve the problem that the existing technology uses a single light source to collect images, affecting image quality, image clarity and detail capture.

[0005] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] The utility model provides a multi-angle combined line scanning light source, comprising a shell and side panels fixedly mounted on both sides of the shell, wherein a bracket is fixedly mounted on the inner cavity side wall of the shell;

[0007] The inner cavity side wall of the bracket is fixedly mounted with a first fixing plate, a first row of lamp beads is fixedly mounted on one side of the first fixing plate, two groups of symmetrically distributed second rows of lamp beads are arranged below the first row of lamp beads, and two groups of symmetrically distributed third rows of lamp beads are further arranged below the two groups of second rows of lamp beads;

[0008] A light concentrating component is further provided inside the bracket, and the light concentrating component is also provided inside the shell.

[0009] Furthermore, the focusing member includes a full-circle focusing rod fixedly mounted on the side wall of the inner cavity of the bracket, and the full-circle focusing rod is arranged on a side of the first lamp bead row away from the first fixing plate;

[0010] The inner cavity side wall of the bracket is also fixedly mounted with an inclined beam splitter.

[0011] Furthermore, the light concentrating member further includes two groups of symmetrically distributed second fixing plates, and the two groups of second fixing plates are both inclined, and the sides of the two groups of second fixing plates close to each other are fixedly mounted on one side of the second lamp bead row;

[0012] Two groups of symmetrically distributed arc reflectors are fixedly mounted on the inner cavity sidewall of the bracket, and the two groups of arc reflectors are respectively arranged corresponding to the two groups of second lamp bead rows.

[0013] Furthermore, two sets of symmetrically distributed third fixing plates are fixedly mounted on the inner cavity sidewall of the bracket, and both sets of third fixing plates are arranged at an angle, and the sides of the two sets of third fixing plates close to each other are fixedly mounted on one side of the third lamp bead row;

[0014] Two groups of symmetrically distributed semicircular focusing rods are also fixedly installed on the inner cavity side wall of the bracket, and the two groups of semicircular focusing rods are respectively arranged corresponding to the two groups of third lamp bead rows.

[0015] Furthermore, a plurality of cooling fans are fixedly mounted on the inner cavity sidewall of the shell, and the other sides of the plurality of cooling fans are fixedly mounted on the surface of the bracket.

[0016] Furthermore, a plurality of groups of outlet connectors are fixedly mounted on the inner cavity sidewall of the housing, and one end of each of the plurality of groups of outlet connectors is fixedly passed through the housing;

[0017] An amplification lens is also fixedly mounted on the inner cavity side wall of the shell.

[0018] Compared with the known public technologies, the technical solution provided by this utility model has the following beneficial effects:

[0019] The utility model can capture more dimensional information in a single motion scan by using three different light sources in the first row of lamp beads, two groups of second rows of lamp beads, and two groups of third rows of lamp beads. Different light sources provide light of different wavelengths, which can illuminate the surface of the object from multiple angles, reduce shadow and reflection problems, especially when the surface of the object has texture, wrinkles or different materials, and can better restore the details. The three groups of light sources scan at different shooting angles and lighting conditions, which can effectively reduce the reflection interference in the image and improve the clarity of the image, especially when detecting surface defects or tiny details of the object, and can obtain more information. At the same time, the stroboscopic technology of the three groups of light sources enables the three images taken each time to be accurately aligned during the movement of the object, ensuring that the illumination effect of each light source does not interfere with each other and avoiding timing confusion between different light sources.

[0028] Specifically, the first lamp bead row 10 and the two groups of second lamp bead rows 11 and the two groups of third lamp bead rows 12 are all composed of a plurality of groups of lamp beads arranged and combined. The light source emitted by the first lamp bead row 10 fixed on the first fixing plate 7 can pass through the full-circular focusing rod 13, and the beam splitter 16 is semi-reflective and semi-transparent.

[0030] Specifically, since multiple groups of lamp beads are arranged in the shell 1, the temperature of the lamp beads is relatively high when irradiated. Therefore, the heat generated inside can be quickly exchanged through multiple groups of cooling fans 5 arranged inside the shell 1, and the lamp beads and other related internal components can be cooled and cooled.

Different light sources provide light of different wavelengths, which can illuminate the surface of an object from multiple angles. The three groups of light sources scan at different shooting angles and lighting conditions, which can effectively reduce reflection interference in the image and improve image clarity. At the same time, the stroboscopic technology of the three groups of light sources enables the three images taken each time to be accurately aligned during the movement of the object, ensuring that the illumination effect of each light source does not interfere with each other, avoiding timing confusion between different light sources, and the amplifying lens 3 not only plays a dust-proof role, but also the light source emitted by the first group of lamp beads 12, one of which is reflected by the beam splitter 16, and one of the light sources can pass through the amplifying lens 3, and the amplifying lens 3 can reduce mirror reflection and increase the transmittance of light.
